Answer:
1100Joules
Explanation:
Workdone = force x distance
Force= 500N
Distance = 2.2m
So, workdone = 500 x 2.2
= 1100Joules
This is not a answer but can’t you just search that up on the internet and get the answer?
Answer:
85 N
Explanation:
Given that crate mass = 20kg
Distance = 6m
Time = 3 seconds
Coefficient of kinetic friction = 0.3
We begin by calculating for acceleration
Which was gotten as 1.33 m/s sq

The average speed of the ball is 0.15 m/s.
The average speed of the ball can be calculated using the formula below.
<h3 /><h3> Average speed: </h3>
This is the ratio of the total distance to the total time traveled by a body
<h3 /><h3>Formula:</h3>
- S = d/t.................. Equation 1
<h3>Where:</h3>
- S = Average speed
- d = total distance
- t = total time.
From the question,
<h3>Given:</h3>
Substitute these values into equation 1
Hence, the average speed of the ball is 0.15 m/s.

Answer:
In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.
Explanation:
There are two ways to connect electrical circuits, in series and in parallel.
Series circuits have the problem that when one element is damaged, the entire circuit is interrupted and runs out of power.
In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.
In Breaker it is connected in series so that when some maintenance is needed, all the energy can be interrupted simultaneously and if some equipment tries to consume a lot of energy, the circuit prevents this action by interrupting the energy of the entire circuit
